Disclosure of Invention
Technical problem to be solved
Among the prior arts as described above, patent document 1 relates to a bicycle driving apparatus that moves a rotation locus of pedals forward so as to be away from a crankshaft when the pedals are at a potential, transmits a strong force to an increased torque of the crankshaft using a lever principle, and patent document 2 is to achieve weight reduction and excellent mechanical strength by reinforcing a part of a frame with fiber reinforced plastic.
The bicycle frame using the related art keeps the buttocks of the user in close contact with the saddle provided at the center to keep the upper body inclined forward, holds the handle bars with both hands and turns, and can be driven by power (thrust) generated by pedaling using both feet.
Due to such sitting posture, the center of gravity is increased during driving, steering is unstable, and the risk of safety accidents in which the user is injured due to frequent falls due to irregularities or the like is high.
Even if the upper body is bent forward during driving, it is limited and thus affected by wind and causes severe resistance, which is particularly noticeable when used as a racing car, having a negative effect on shortening the record.
In addition, since the power that the bicycle can drive is generated by the combination of the sprocket and the chain, there is a limit in enjoying a quick game or speed even if the speed is increased by the speed change.
Especially, power is transmitted through a chain connection between a main chain gear fixed to a pedal shaft installed at the center of a vehicle frame and a driving sprocket installed at a rear wheel shaft, so that power loss occurs when a user's force is not completely transmitted, and thus it is a cause of rapid fatigue of the user's body.
In use, there are various problems in that the chain is subjected to considerable stress, resulting in breakage of the chain, causing safety accidents, requiring a great deal of time and money for repair and maintenance.
Technical scheme
Accordingly, the present invention, which is invented to solve the above-mentioned problems, comprises a frame 110 on which a front wheel 101 and a rear wheel 102 are mounted and on which a user rides;
the speed increasing device 130 is installed on the rear wheel, generates power and increases speed by stepping on,
riding on the bicycle through the state that the user pronates reduces the focus, improving driving stability, improving the speed of a motor vehicle through reducing air resistance at the driving in-process to on easily transmitting user's power the footboard, can reach the purpose that increases thrust and produce.
Advantageous effects
The present invention has the effect of improving driving performance by constructing the frame so that a user can ride in a prone position, increasing stability by lowering the center of gravity, and reducing resistance during driving.
The present invention can increase the speed by the speed increasing device directly connected to the pedal at the center of the rear axle to minimize the power loss, and can be operated by the cover installed at the frame, thereby providing various effects of the advanced bicycle.

Detailed Description
The bicycle 100 to which the technique of the present invention is applied includes: a frame 110 to which the front wheel 101 and the rear wheel 102 are mounted and which a user can ride; and a speed increasing device 130 mounted on the rear wheel and generating power to increase the speed by stepping on.
The frame 110 has an upper tube 113, the upper tube 113 being connected to an upper side of a head tube 112, the head tube 112 being rotatably mounted on a suspension tube 111, a front wheel 101 being mounted on the suspension tube 111, and a lower tube 114 being connected to a lower end of a distal end of the upper tube 113 in a rearwardly inclined manner.
A center tube 115 is longitudinally connected to rear ends of the upper tube 112 and the lower tube 114, a rear tube 116 is connected to an upper end of the center tube 115 to be inclined downward, a bottom tube 117 extending horizontally toward the rear is connected to a lower end of the center tube 115, and rear ends of the rear tube 116 and the bottom tube 117 are in contact, so that the rear wheel 102 can be mounted.
In order to reduce weight, the frame 110 is preferably made of reinforced aluminum or carbon, and a flat portion 120 having a width of 14-40cm is formed on the upper surface of the upper tube 113, so that the user's chest and abdomen portions are stably connected and supported.
Shoulder hooks 121 are integrally formed at the front side of the upper tube 113 to receive and support both shoulders of the user in a prone position, and a seat part 122 for supporting the hip part of the user at the rear end of the upper tube 113 is integrally formed by being protruded upward while being inclined rearward.
There are cushion pads on the surfaces of the flat portion 120, the shoulder hooks 121, and the seat portion 122 to absorb shock and vibration while increasing the close feeling.
The handles 125 are installed at both sides of the upper side of the hanging pipe 111 so as not to interfere with the head pipe 112 to achieve steering, and are not designated as any one shape since the shape of the handles 125 may be changed.
The speed increasing unit 130 transmits power in a forward direction by inserting one-way bearings 132 into main brackets 131 mounted at ends of the rear tube 116 and the bottom tube 117, and a pedal shaft 133 which can be idly rotated in a reverse direction is held, and pedals 134 are coupled to both sides of the pedal shaft 133.
A motor gear 135 for generating power by rotation of the pedal shaft 133 is mounted or integrally formed at one side of the pedal shaft 133, and an intermediate gear 139 provided at one side of a switching shaft 138 and a bearing-engaging speed-increasing gear 140 interposed in an auxiliary bracket 137 held between the main brackets 131 by a support 136 are mounted at the intermediate gear 139 side.
The speed-increasing gear 140 is engaged with a drive gear 141 mounted on the pedal shaft 133 on the side of the motor gear 135 via a bearing, and outputs the power after speed increase, and the drive gear 141 is used to drive the rear wheel 102 via a hub 142 to which the rear wheel 102 is fixed.
The prime mover gear 135 is larger than the intermediate gear 139, and the speed increasing gear 140 is formed to be larger than the prime mover gear 135 and the intermediate gear 139 so that the minimum driving gear 141 can be rapidly rotated, a corresponding gear ratio is calculated in consideration of a desired speed, and a brake disc for braking can be mounted on an outer surface of the hub 142.
When wanting to ride the bicycle 100, the prone posture is taken such that the user's abdomen and chest are brought into close contact with the flat portion 120 formed on the upper surface of the upper tube 113, the shoulders are brought into close contact with the shoulder hooks 121 formed on the front side of the upper tube 113, and the buttocks are brought into close contact with the seat portion 122 formed at the rear of the upper tube 113.
Of course, the direction is adjusted by holding the grips 125 formed at both sides of the upper end of the suspension pipe 111 with both hands, and when driving in this state, it is possible to push forward on the ground with both feet, or push down with one foot on the ground and the other foot with both pedals.
When starting the running, the motor gear 135 is rotated by stepping, the power of the motor gear is transmitted through the intermediate gear 139 and the speed increasing gear 140 mounted on the switching shaft 138, and finally, the speed is increased faster than the stepping speed of the user by the driving gear 141 mounted on the pedal shaft 133 regardless of the rotation of the pedal shaft 133.
Since the hub 142 is mounted on the driving gear 141, the rear wheel 102 can be finally rotated and driven, and if necessary, can be used for racing to compete for speed by mounting the cap 150 on the outer side of the frame 110 to be driven even in rain and snow.
In particular, the present invention allows the user to maintain a comfortable posture by keeping the user in a prone position, and allows the power to be transmitted without any loss during stepping by using the lower body, thereby maximizing the power transmission and power generation efficiency.
Industrial applicability of the invention
The present invention according to the above has various advantages of lowering the center of gravity and increasing the driving stability by allowing the user to ride in the prone position of the bicycle 100, reducing the air resistance during driving to increase the speed, and increasing the generation of the thrust by facilitating the transmission of the user's force to the pedals 134.
